SPECIFICATION forming part of Letters Patent No. 423,622, dated March18, 1890.

Serial No. 266,086. (No model.)

.To all whom it may concern.'

Be it known that I, DAVID AMBRosE MUR- RAY, a citizen of the UnitedStates ot' America,

, residing at Princeton, in the county of Mercer andState of New Jersey,have invented certain new and useful Improvements in Type-WritingMachines, of which the following` is a specification, reference beinghad therein to the accompanying drawings.

This invention pertains to certain new and useful improvements intype-writers, having for its object, primarily, the production of atype-writer embodying means whereby a rotating type-wheel `and theoperating keys or levers are relatively arranged so that pressure upon acertain key will stop the revolu- .tion of said type-wheel when the typecorre` spending tp said key is at a given point.

A further object of the invention is the provision of simple andefficient means for revolving the type-wheel in such manner that thesame can be stopped at the desired point,

and by reason of its acquired momentum will eect the printing of thedesired letter and at the'sarne time the operating parts continue theirmovement, whereby after the printing of the said letter the type-wheelwill continue` in its revolution without requiring additional force tostart it and at the Sametime avoid the strain consequent upon suddenlystopping said type-wheel.

A further object of-t-he invention is the .provision of a new and.improved forni of and particularly pointed out in the claims,

whereby a typewriter is produced that embodies advantages in point ofsimplicity, durability, and general etlicienoy. Y

In the accompanying drawings, Figure 1 is a plaiiview of my invention.Fig. 2 is a front elevation thereof. Fig. 3 is a central longitudinalsectional view taken on the line Fig. 1.

Fig. 18 is an enlarged detail sectional view anenlarged perspective view of the typewheel, showing the positionoccupied by the wheel. Fig. 2O is an enlarged detail view of one end ofoneof the be1lcrank levers and a portion of one of the escapeinentdevices, andl Fig. 21 is a view showing the movable board of thepaper-carriage frame. Fig. 22 is a a detail View of the paper-carriagestop-bar.

Referring to the drawings, A designates the frame or table oit mytype-writer, the saine being supported by suitable frame-work or legsconnected by a cross-rod a. To the frame or table are secured the sideboards ot' what I terni the linger-board a2, the upper rear portion ofwhich has connected thereto a iiat horizontal bar 0.3, and to the uppersurface of this horizontal bar as are connected the ends of anoverhanging bar a4, as shown. Upon this bar as is secured acircularly-arranged ink-pad a5.

Upon the table A, in rear ot the fingerboard, is disposed a movableboard B, one

by a short stud b, and its other end has formed Fig. 12 is a view inside elevation plan view of the operating-levers. Fig. 23 is wheels.Fig. 13 is a sectional view of said es-V 15 is an enlarged perspectiveview of one of* Si the type. Fig. 16 is an enlarged plan Viewl of oneend of said papercarriage Fig. 19 is f type when forced by the upperdisk of they "f end of which is loosely secured to said table i p e423,622

'ygtherein a cam-like opening b', wherein works a correspondingly-shapedend of a shifting- ."-lever C, the outer end of which extends to #thefront end of thctable A and is capable f of being moved or operatedbythe knee of the operator.

By means of this lever the rmovable board can be moved or shifted to-"wardthe front or rear of the table, as shown.

`D is the paperlcarriage, composed of two vertical end bars- C C2,connected at their lower ends by a bar 2 in grooves, in the under sideof .which are hung pulleys 3 3, designed toy roll upon guide-bars 4 4,rigidly secured at their ends to upwardly-projecting bars or uprights 55, rigid with the movable board B. Between the uprights C C2 is secureda paper roll or cylinder 6, the ends of which are jou'rnaled in' saiduprights and it has secured upon one end a ratchet-wheel 7, with whichengages one end of a pawl 8, pivotally secured to one end of a lever 9,fulcrumed at its rear end to the inner side of the upright C2.

A spring bears against this pawl 8 to 'hold the same in engagement withthe wheel 7, and asimilar spring 11 bears against the under side of thelever 9 to normally hold said lever elevated against a pin or stop v12,inserted in any one of a series of holes 13 in the upright C2, thedownward movement of said lever 9v being limited by a similar pin orstop 14, also inserted in one of said holes 13. By means of these pinsor stops the extentv of the i ,revolution of the paper wheel or cylinderis regulated.

-E is a cord connected at one end to the le- 'ver 9, and is passed`around a small roller e,

hung in an opening of the upright C2, and after being passed through ahole or opening ,for -a purpose to be described.

in the table A is connected to one end of a treadle F, fulcrumed uponthe cross-rod a', In each of K' these uprights C2 is formed an opening15,

`through which an endless belt 16 is passed, .said belt being passedaround a roller or wheel G, keyed upon .a shaft g at right' anglesthereto, and'also around a roller or wheel g',

' mounted between two armsg'2`, secured to the outside of one of thevertical uprights 5, said l belt being also passed through openingsformed in said uprights 5 near their lower ends, as shown. y

H is a spring-held arm pivotally secured Y between two vertical plates hh, attached -to the outer side of the upright C2, and against its outersurface bears a spring h', whereby 'said 'arm is normally held close tosaid end upright.

The lower end of this spring-held arm is beveled and normally bears uponthe endlessbelt 1 6, holding the same irmlyagainst 'the upper side ofthe lower connecting-bar hf of the arms h, wherebya .firm connection isestablished between the paper-carriage and the endless belt.

- 'The cord E after being passed around the roller e has secured thereona button or stop 18, which always bears against the inner sur-` face oflthe arm H over the aperture formed therein, through'which saidcordis-passed-u whereby the lever 9 has a fixed movement', withrelationv to said arm H. A stop-barl is secured upon the guide-bars 4 bysuitable means-such asv set-screws-to regulate the J is a treadlepivotally securedupon the y cross-rod a of the frame, and has connectedthereto one end of a pitman 24, connected at its other end to afly-wheel 25, around which around two rollers 27 27, secured in thetableA, from which said belt is passed in a horizontal direction around aband-wheel or puli y 9C4 r.

ley 28 on the shaft of a horizontal wheel 29, and around this wheel 29is passed a second endless belt 30.

K is a type-wheel composed, preferably, of I l two parallel disks 7cla', the lower one of which is rigidly secured to a vertically-disposedshaft k2, extending through an aperture in the horizontal bar a3, andupon its lower end said shafthas loosely secured thereon a bandwheel 31,around which is passed the endless band or belt 30. To the upper surfaceof this band-wheel 31 is secured a circular casing 32, wherein isdisposed a long coil-spring 33, se; cured at one end to the shaft k2 andfat its. other end lto said band-wheel, which itself has no directconnection with said shaft save through the coil-spring The object ofthis arrangement is to avoid the strain consequent' upon the suddenstopping of the type-wheel,

and to provide means for imparting addi-` ['IO tional force to saidtype-wheel whenitf is again set -in motion, in the manner tofbehereinafter described. I- I The lower, disk 7c is secured to the shaft7c? by means lof an apertured nut ks, keyed to. i g

said shaft, said nut having ony its outerl lsurface two screw-threads7a4 h5. The disk" c ,-af`

IOO A ter being placed down upon the shouldered a rigid connection withits shaft k2, while the disk 7c is loosely connected therewith. Asuitable spring 34, connected at its ends tothe opposite faces of thedisks k 7a', forms a connection between the same. To theunder'side ofthe lower disk 7s are secured or formed inr I tegral therewith twoopposite downwardlyprojecting lugs 35 36, formed on circlesadja- `125this it will be seen that the lower disk lc has extent ofmovement ofthe-paper-cari'age.-` y This stop-bar is shown in detail in Fig. 23.

To the upper side of the movableboard Bv l l passes an endless belt 26,which is passed 'cent each other, the latter being within the former.

L' L are two series or rows of type carried by the type-wheel, the typeof each series being adjacent to each other. Each type consists of anormally-vertical bar` l, pivotally secured at its lower end in anaperture in the lower disk k of the type-wheel, and from this f zo barprojects an outWardly-inclinedarm Z,.

having' a vertical portion Z2 projected through a preferably circularhole inl the disk 7c', ajid uponlits lower end is secured or cast there--with a type, as shown at Z3, Fig. l5. The upper ends of the bars Z ofthe type are extended through adjacent openings l4 Z4 in the upper diskla, and are free to have playin said openings. A slightly-curved lever Mis fulcruined' at its center about midway between the open ings Ziof theupper disk, the ends of which project a slight distance over saidopenings, as shown.

NIN are two series of circularly-arranged vertically-disposed stop-pinsdesigned to project through correspondingly-arranged holes in thehorizontal bar a3. The upper ends of each series of stop-pins aredesigned to be on a line with the lugs 3G, respectively, of the Y lowerdisk of the type-wheel.

To these stop-pins N N are designed to be connected the forward ends ofhorizontallydisposed main operating-levers n, fulcrumed at about theircenters on short posts a', pro- ,jecting from the table A, said leversbeing disposedunder the finger-board, and converge toward their rearends. In the front portion of the finger-board are formed a series ofopenings, through which` extend the connecting-necks of the operatingkeys or levers O, said keys being bent into an approximately V shape andfulcrumed at The lower ends of said keys or levers O are designed tobear upon Vthe ends of the series of levers n, one key or lever beingprovided foreach of the operating-levers n.. Upon the outer surface ofeach of these operating keys or levers O is indicated or stamped aletter, numeral, or punctnation-mark corresponding to the similarletter, numeral, or punctuation-mark ofthe type of the type-wheel. Theseoperating keys or levers O are disposedin groups so located and arrangedthat each of the ten fingers of the operator will have a set or gro upof keys upon which to act, and thus the operator is enabled to operateall the keys without moving his hands, and in practice he can alwayskeep his eyes upon the text from which copying, whereby greater speedand ease of operation is attained.

By depressing the outer portion of an operating key or lever O the samewill, through respective lug 35 or 3G of the lower disk of the.

type-wheel will strike against or come in contact with said pin, thusstopping the movement of the type-wheel, at least its lower disk. P Pare two bell-crank levers arranged within the linger-boardunder the mainoperfulcrumed at their ends at one side of the finger-board, and arealso fulcrurned near their other extended ends. The outer armsating-levers n, and said bell-crank levers are.

37 37 of these levers' are loosely connected with the central portionsof pivoted levers Q p Q, which are fulcruined at their outer ends to thesides of short posts or uprights 38 38,

projecting from the table A near one side thereof.

capement devices is composed of a large pinion 40, loose upon shaft g,adjacent to which is a drum 4l, having a toothed portion 42, with whichengages a spring-held pawl 43, pivoted to the pinion 40, and around thisdrum 4l, which is also loose upon the shaft g, is passed a cord 44, toone end of which is connected a suitable weight 45, (or it may beprovided with a spring) and the other end of said cord 44, after beingpassed a numberof IOC times around the drum 4l, is passed around rollersor pulleys 46,attached to the tableand connected to the treadle F.Adjoining each drum 4l is a second ratchet-wheel 47 rigidly secured orkeyed to the shaft g, with which they are designed to revolve, saidratchet-wheel being also engaged byaspringheld pawl 48. Each pinion 40is designed to engage one end of a pawl 49, fulcrumed at its other endto the adjoining post 3S', and with the inner curved surface of thispawl 49 engages the outer hooked end of each lever Q. These escapementdevices are exactly the saine in construction, except that there are agreater number of teeth or serrations on one pinion 40 than on theother.

The ,levers n (hereinbefore referred to) arr made to rest or bear someupon the bell crank lever P and the others' upon the bel crank leversP', whereby upon operating-a one of the operating-keys O, causing the dpression of its respective lever u, one of the bell-crank levers uponwhich said lever n bears will be depressed, causing' the arm 37 thereofto operate kupon the lever Q, which will effect the disengagement of thepawl v49 from one of the teeth of the pinion 40, whereby said pinionwill be caused to revolve consequent upon the weighted cord 44 to theextent of one tooth of said wheel, the displacerof ment of said pawlcausing the same to occupy the position shown in Eig. 7 sufficient topermit of the partial revolution of the wheel 40, and the tooth justdisengaged will come in.

- contact with the bent end of the lever Q, i causing the elevation'thereof and the conseyquent engagement of the pawl 49 with the nexttooth of the pinion 40. Immediately 5 upon the lever Q assuming itsformer-position the previously-depressed bell-crank lever will beelevated, as will also the frontend f of the levern, which will effectthe retraction of the respective stop-pin. o The object of having two ormore cranklevers and escapement devices, together with the peculiarmanner ofdrawing the paper-carriage, is t0 provide means for securinglonger kor shorter spaces between wider or narrower 5 letters, thelevers of all narrow letters being i fulcrumed on one bell-crank leverand ,those nof the wider letters on the other corresponding bell-cranklever.

From the foregoing description it will be o seen that the disengagementof but one of the two series of escapementwheels will not prevent thepartial revolution of the shaft g, i since if the pawl 49 of the otherSeries is in engagement with its pinion 40 only the Wheel 5 or pinion 47of said latter series, which is ft' fixed firmly to the shaft, willrevolve, and its spring-held pawl will slip over the teeth or Vserrations, dropping into Y a notch when it v stops. p oy or pinions 47of each series of escapement ldevices are very fine or made closetogether, so that when the movement of the shaft ceases 'both pawls 48will be practically in` engage ment. Whichever of the bell-cranklevers-is 5 operated upon its respective escapement devices will effectthe partial revolution .of the "l Shaftg the desired distance, whileeach esv capement device will move the shaft the distance appropriatedto it. i yo If desired, he wheels 40 and 41 of each escapement devicemight be all one piece. The object in making them in the mannerdescribed and shown is that the pinion 40 will not have to be turnedback in windingl the .5 'weighted cord upon the drum.v

It will be seen that the turning of the shaft q will effect the turningof the wheel G, and through the belt 16 will effect the movement of thepaper-carriage toward said wheel Gr, carrying the paper under the holeor 'aper ture 23 in the stiff sheet or board 2l.

In practice motion is imparted to the typeheel by an operator workingthe treadle J, '.'hich through the Wheel 25, belt 26, horizon- J5 talwheel 29, and belt 30 will effect the revolution of said type-wheel andits" shaft 7a2, which wheel revolves at a rate from'ten to thirtyrevolutions per second, except when 1t is checked or suddenly stoppedfor an instant in the manner to be described, and then the power thatwould naturally be communicated to the revolving type-wheel is takenupby -f the coil-spring 33, attached to theband-Wheel 3l, `whereby anyjar or strain upon said typewheel is prevented when the same 1s suddenlystopped, and the winding up of the spring at The teeth or serrations ofthese wheels connected thereto# this time will give additional forceiofsaid 'i' type-wheel, when the same is again released.

in the sti sheet or board 21. Motion! being imparted, as above detailed,tothe typewheel and the paper being in position,the

operator, by pressing upon that lever representing the type to beprinted, will eect' the elevation of the respective stop-pin N or Nthrough the agency of the levers n, which pin will instantly come intheline or path`0f thatone ofthe lugs 35 or 36 of the type-wheel withwhich it corresponds, thereby when said lug strikes said pin stoppingimmediately the revolution of the llower disk of the type-wheel, and byreason of the momentum of the upper disk the same will bear tightlyagainst the upper ends ofthe vertical arms Z of the type L, causing. thedepression of the same and the forcing of the type down upon the inkedpad a5 or stiff sheet or board 21, while thatv type alone correspondingto the letter of the key depressed will proj ect through aperture 23 andleave its impression on the paper on the roll or cylinder, immediatelyupon which said vupper disk of the type-Wheel will be brought back toits proper position by reasonof the spring 34y Simultaneous with `thislast-described operation the lever n eected the depression of that oneof the bellcrank levers P P' upon which it bears, causing thedisengagement of the respective pawl 49 with i the pinion 40, permittingof the partial revo lution of the shaft g, which, through the` yagencyof the endless belt 16, eected the movement of Athe type-carriage thespace of one letter, so asto present the paper to the opening 23 for theimpression of thesecond type. Upon the elevation of the outerend of thelever Q of that one of the escapement devicesv operated upon thebell-crank levery resumed its former position, causing the lowering ofthe forwardend of the lever n, and consequently the retraction of thepreviouslyelevated stop-pins, wherebythe type-wheel y i x15 can bestarted on its revolution without any additional force being required byreason of the powe'r obtained by the winding of the spring 33. Theoperator continues this opere ationuntil the entire line is printed.During the movement of the paper-carriage from right to left that end ofthe treadle F to which the cord E and the weighted cord 44of theescapement devices are connected was clevated, and consequently by theoperator depressing the end of said treadle the lever 9,

IZO

to which the cord E is connected, will be lowered into the positionshown in Fig. 18, causing through the pawl 8 the revolution -of thepaper roll or cylinder, and the springheldarm l-l is withdrawn fromcontact with the endless belt 16, and the carriage is then moved backover its guide-bars 4 until it comes in .p e'onmetwith the thedepression of the treadle F stop I, and`at the same time effected the.rewindiug of the weighted cord on the drums hand the upper disk `4landthe device is now in -thc position ready for the vprinting of anotherline in a manner similar to that above detailed.

' The office of the levers M, pivoted on the type-wheel, is that whensaid type-wheel is stopped in its movement, forces the upper ends of thevertical bars of the type forward, if either i l one of said type comesin contact with one of the lugs 22, as one must, one end of sa leverwill consequently be impaired in its movement by contact with the end ofthe bar of that one of the type in contact with the lugs, causing theforcing forward of tlie other end of said lever, which will forceforward to its full' extent the upper end of the bar of that one of thetype whichextended through the opening 23 and make its impression uponthe paper. All the type save that one whichv 1t is designed to impressupon the paper strike upon the upper surface of the stiff paper or board2-1 or upon the ink-pads a5. rlhe type of the inner circular series ispreferably composed of capital letters and some punctuation-marks, whilethat of the outer series is composed in the main of small letters. Thetype ofi said latter series pass normally Vover theV opening 23; but toprovide means for printing capital letters I have made the board Bmovable, whereby the operator, by shifting will make other l 1 and theadjacent type will strike, as capital the lever C by his knee, willshift the board B, as shown in dotted lines, Fig. 21, whereby the typeof the inner series, when operated upon by the operator depressing thekeys, impressions upon the paper,

letters did previously, upon one of tions 22. To avoid printing ters atan angle by reason the proj ecthe capital letof shifting the p board B,the type thereof are preferably placed on a slight angle.

It is obvious that, if desired, I can employ in lieu of the bell-cranklevers P P for operlating the .escapement devices a separate lever u',connected with each one of the levers n',

and which operate upon the tripping-lever Q', Whlch in this instance isfulcrumed at its v center, and is engaged at one end by the con- 's'sAvergent ends of said series of levers, as shown in Figs. 4 and 7.
